Apple released iOS 4.1 on Wednesday for the iPhone and iPod touch. The update includes several new features such as Game Center, HDR photo capture, HD video upload support and TV show rental support.
The update is compatible with the iPhone 3G, iPhone 3GS and iPhone 4, as well as every iPod touch after the first generation model. Not all iOS 4.1 features, however, are compatible with every device.
iTunes iOS 4.1 update dialog
To download and install the update, launch iTunes on your Mac or Windows PC and connect your iPhone or iPod touch. If an update dialog doesn’t appear, select your iPhone or iPod from the Library list, select the Summary tab, and click Check for Update.
Some users are reporting on-again-off-again availability of the update, so you may have to try more than once to get the update to show up in iTunes.
iOS 4.1 is a free update for iPhone and iPod touch users, and weighs in at 589 MB. iOS 4.2 will be available in November and will include iPad support.
